hey guys question putting a machine back together from a mechanic who walked off the job. Mechanic pulled pump to be sent out for rebuild ECM/pump/INJ returned rebuilt. i dont have the FIR # from the old unit and the new one doesnt have a stamped number on it. can i assume 50 to 60 is a good value to start with? ALSO the mechanic pulled the 4 bolt gear off the tapered/keyed hub that goes onto the shaft so i lost the timing. i know how to set it based on plunger projection in the plugged port on the head. BUT i do not know where the IP is sitting at any moment in time. The shaft rotates 360* and i assume every 90* is an injection event being its a 4 cyl. is a MP style pump "mono plunger" so is every compression of the cam in the pump just compressed fuel and another device controls delivery to said injector or is every 90* a specific injector and if so how can i lock the pump at #1 TDC as i see no pin hole in the housing to lock in the hub? thanks
